Product was formed successfully based on the exp. below (about
85% yield), please interpret/discuss HNMR/IR in as much detail as
possible and assign peaks on HNMR (which peak represents which
protons of which group, etc). Note: I already know how you
determine the formation of the product so you can skip that part of
part b).
Based on this exp:
Discuss the IR spectrum and what is the peak in IR that you can see for a specific functional group...
Questions 2-10 please!!
1) A substitution reaction is: [2] a) A reaction during which an OH group of a molecule is replaced by a halogen. b) A reaction during which water is the leaving group. c) A reaction during which a functional group of a molecule is replaced by an electrophile. d) A reaction during which a functional group of a molecule is replaced by another functional group. V 12 2) Substitution reactions are classified either as electrophilic or nucleophilic...
Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

FTIR and NMR Spectra After completing a reaction and working up the products, it is still necessary to confirm that the correct product was formed. The most common tools used for this analysis are Fourier Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy. In the virtual laboratory, 'H and C NMR spectra are available. Details on interpreting FTIR and NMR spectra are found in your textbook. Your instructor may or may not...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
